Recommended RAID configuration for domain controller Redundant array of independent disks (RAID) can be used for fault tolerant and to prevent single disk failures, if you have more then 1000 users accessing the domain controller then , place the log files on one RAID 1 array and keep the SYSVOL shared folder and the database together on a separate RAID 1 array. If you have less then 1000 users accessing the domain controller then you can place all the components in a single RAID 1 array, components are OS, log files, SYSVOL, Database Disk Space Recommendations for active directory installation Domain controller requires available free disk space for OS, log files, SYSVOL, database. Follow the below procedure to calculate the disk space requirement for domain controller (active directory installation) • On the drive that will contain the Active Directory database, Ntds.dit, provide 0.4 gigabytes (GB) of storage for each 1,000 users. For example, for a forest wi...

O   Orgabizational Structure : OU can be populated of many types which objects . 1. Computer 2.Users 3.Groups 4.Printers 5.Sub Organizational Units

What is Domain in Active Directory?  Active Directory is the collection of computer,users, and group of objects defined by administrator.These object share a common directory database ,securtity policy and security relationship with other domain.

 Ques. What is the structure of AD(Active Directory)?      Ans. There are two types of Structure:   1. Physical Structure   2. Logical Structure Physical Structure contain Domain Controllers and sites. Logical Structure contain Tree,Forest,domain and organizational unit.  Below is the Hierarchy : Forest ==> Tree ==>Domain ==> Child Domain==> Grand Child Domain Tips for Active Directory :  Active Directory design is a science, and it's far too complex to cover all the nuances within the confines of one article. But I wanted to share with you 10 quick tips that will help make your AD design more efficient and easier to troubleshoot and manage. 1: Keep it simple The first bit of advice is to keep things as simple as you can. Active Directory is designed to be flexible, and if offers numerous types of objects and components. But just because you can use something doesn't mean you should. Keeping your Active Dir...

What is Active Directory ? Ans : It is an Hierarchical Structure which stores : a.Computer Information b.User Information c.Network Information d.Directory Data e.and Make data available to users and administrator in network. The core of active directory is the combination of LDAP and Kerberos running on Windows server and acting as a domain controllere that work unite to provide authentication and authorization information within group of interlink system..

Why C and B Class Subnet is used in some industry on A Class IP : Eg : IP Assigned in Company X is 10.20.1.1 and its subnet is 255.255.0.0 Try to find your answer below tutorial. CIDR or Classless Inter Domain Routing provides the flexibility of borrowing bits of Host part of the IP address and using them as Network in Network, called Subnet. By using subnetting, one single Class A IP address can be used to have smaller sub-networks which provides better network management capabilities. Class A Subnets In Class A, only the first octet is used as Network identifier and rest of three octets are used to be assigned to Hosts (i.e. 16777214 Hosts per Network). To make more subnet in Class A, bits from Host part are borrowed and the subnet mask is changed accordingly. For example, if one MSB (Most Significant Bit) is borrowed from host bits of second octet and added to Network address, it creates two Subnets (2 1 =2) with (2 23 -2) 8388606 Hosts per Subnet. The Subnet...

What is ADFS (Active Directory Federation Services)? up vote 13 down vote favorite 5 So I've been told that our PHP application may need to support authentication using ADFS. For a non-Microsoft person, what is ADFS? How does it differ to things like LDAP? How does it work? What kind of information would be included in a typical request to an ADFS server? Is it designed for both authentication and authorization? Are ADFS servers typically accessible from the internet (whereas corporate AD domain controllers would not be)? I've tried reading some of the Technet docs, but it's full of Microsoft-speak that isn't hugely helpful. Wikipedia is better (see below), but perhaps some of the ServerFault community can fill in some of the gaps. Active Directory Federation Services (ADFS) is a software component developed by Microsoft that can be installed on Windows Server operating systems to provide us...

Microsoft Licencing : Well, there's a big difference between a Device and a User CAL. ·          Device CALs provide access to a "device" (namely a client computer most of the time), no matter how many different users have login access to that device. ·          User CALs provide access to a "user",that can login from as many "devices" as he wants. So, how to decide? Depends on your architecture. The rules are simple: ·          You have more devices than users accessing the database: buy "user" CALs. An example of this might be an organization where you have just 3 users connecting to the server using any of 10 computers (not a far-off case, considering laptops, other servers, etc.). ·          You have a lot of users accessing a server through an small set of devices: buy Device CALs. An example of this wo...
